Krolmir, Hammer of Storms

Krolmir, Hammer of Storms is the personal weapon of Thorim the Stormlord.

When Thorim's wife, Sif, was slain by his brother Loken, Thorim threw the hammer to the earth with all the power and rage he possessed, creating the site now known as Thunderfall.[1]

As his final act, King Arngrim cast a rune on the hammer to prevent his enemies from claiming it. When Thorim's ties with the Sons of Hodir were strengthened, many years later, King Jokkum returned the hammer to its rightful owner.[1]
